Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and slide the caliper off the rotor.
Hang the caliper using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Compare the thickness of the new brake pads with the old ones to ensure proper fit.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged or worn, remove the rotor by unscrewing the retaining screws (if equipped).
Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
Install the new rotor, ensuring it sits flush against the hub.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque setting (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from jack stands and tighten the lug nuts to the specified torque (usually 80-100 ft-lbs).
Reconnect the battery.
Pump the brake pedal several times to seat the brake pads against the rotor.
